Specification of Letters Patent No. 22,633, dated January 18, 1859.

To all whom it may concern:

Be it known that we, L. J. DronasoN and J or-IN FRAZEE, of Georgetown, in the county of Brown and State of Ohio, have invented a new and useful Improvement in Machinery for Turning Spokes, dc.; and we do hereby declare the following to be a full, clear, and exact description thereof, reference being had to the accompanying drawings, and the letters of reference marked thereon, making part of this specification.

Similar letters refer to like parts.

Our invention consists in certain improvements in machinery for turning spokes etc.7 described specified and represented as follows.

By reference to the accompanying drawings, Figure l, exhibits the front of the machine in perspective, with all its parts arranged for operation. Fig. 2, shows a section taken vertically through the machine at a point indicated by the red lines (0c, m), and exhibits the machinery for holding the spoke to be turned, and also the cutter frame and its cutters while in position to act upon the pattern and spoke in cutting', as hereinafter fully explained. Fig. 3 is a detached portion of the cutter frame and screw, showing the sliding catch in gear with said screw.

(A) is a frame for supporting the machinery (B) is a screw shaft for giving motion to the carriage ('O) which slides in grooves in cross pieces (D, D) of the frame (A). The screw (B) is turned by a pulley wheel which is operated by a band passing over the small pulley (F), on gear shaft This shaft has a large band wheel (I-I) which turns loosely when out of gear with the spring clutch (I) for the purposes hereinafter explained. The cutter frame (J) with its rotating cutters (K) (these cutters are operated by the drum K) are hinged to the sill of carriage (C) at (a), and on the top of this frame (J) is an adjustable bearing plate (b) which is made to bear against the pattern spoke (c) by means of springs (cl cl) attached to the upper part, and extending back from the cutter frame (J) and pressing against upright posts (e c). These are all attached to the carriage (C) and move with it, when the adjustable sliding catch (f) is in gear with the screw shaft (B). On the opposite side of the carriage (C) shown clearly in (Fig. 2) is another frame` (L) hinged, and operating in the manner described for the cut-ter frame (J),

and is provided with an adjustable bearing plate (g) bearing against the pattern spoke (c) but placed to one side of the cutters on frame (J). This frame (L) supports an emery wheel (it) turned by a band (L) which passes over the drum (z.), so that its periphery will rub againstthe spoke after the cutters (K) have performed their operation, and thus the spoke will be completely finished and smoothed before leaving the machine.

Near the bottom of the frame (L) is pivoted a spring lever (M) which projects to the top of the frame, and alongside of it is pivoted an adjustable piece (N), and to this piece (N) is pivoted two levers (N, N,) having their fulcrums at said pivots. They project a short distance and are connected together by an adjustable connecting rod (O). This rod (O) is made adjustable in two ways, vertically and transversely, so that the rests (N, N,) can be adapted to any size of spoke, to be cut, and at the same time be pressed against the spoke firmly, during the operation of turning and prevent it from trembling. )Vhile the cutters (K) are performing their work the ends of these rests (N N) are held up against the pattern (c) and spoke (s) by means of a connecting rod (P) fastened to the bottom of the traveling carriage (O). Across the center of the upper frame work of the carriage (O) is a shaft (R) upon which are two bent arms (R, R)-projecting in opposite directions, and on the end of this shaft is a bent lever (Rm) which extends out under the cross piece (D) of the frame (A) so as to be convenient for the operator, who when a spoke has been completed presses this hand lever down, which forces the arms (R, R) alternately against the frame (J) and cutter frame (L), pressing out the two frames with their cutters, and emery wheel (71,) and releasing them from the pattern (c) and spoke (8'). This operation also relieves the sliding catch (f) from the screw shaft (B) so that the spoke can be removed and replaced with another piece of wood to undergo the operation of turning and smoothing.

When a spoke has been finished and the cutters returned as shown above, it is necessary to stop the motion of the holders (s, s), and for this purpose we adopt the following arrangement: The machinery for supporting the spoke pattern (c) and spoke (8') is mounted in a framework (T), which eX- tends across the main frame (A) above the table and traveling carriage (C). On one end of this frame (T) is arranged a set of spur wheels (i, z", i), the two outer wheels having their bearings in an upright piece (T) and the vertical post (A) of the main frame The shaft of the inner wheel bears on the upright piece (T) and passes through the post (A) and has a pinion pulley wheel keyed to it (F)-and also a large pulley which will turn loosely on the shaft. The shaft has its other bearing in a pillar (A). Between this pillar (A) and the pulley wheel (H) is a clutch (T) which plays back and forth on its shaft (G) and meshes into projections (j, j) on the side of the pulley This clutch is held against the pulley by a spiral spring (k) operating upon lever (K) pivoted at (y) to pillar (A). This lever projects above the top of said pillar and near its extreme end it is attached to a long rod (Z) which is bent forward and extends across the frame (A) to the post (A), where it is held up by loop (Z). The rod (Z) has a catch (Z) which hooks into the loop (Z) when lever (K) is thrown back and throws the clutch (I) out of gear with the pulley (H) and allows said pulley to revolve loosely upon its shaft. This is effected when the carriage (C) is brought back to the starting point by its coming in contact with the projecting portion of the spring catch (m) which relieves the spring arm (nl) and through the medium of the pitman rod (nf) the bent portion of lever (1W) comes in contact with the lever (K) and forces it forward, thus relieving the pulley (H) from the clutch (I) as above described, and stopping the motion of the spoke (s). When the operation is ready to be repeated the attendant raises the hand lever (Rm) which brings the sliding catch (f) into gear with the thread of the screw (B).

The carriage (C) is then started, and in passing the spring arm (n), raises the same which is then caught and held in this position by the spring catch (m) which throws the pitman v(u) up and forces the arm of the bent lever (71W) back, relieving it from the lever (K). The rod (Z) is then relieved, and the spring brings the clutch (I) against the pulley wheel (H) and throws it into gear with the machinery hereinbefore described, andthe operation of turning and smoothing thus goes on again.

By adjusting the several parts, above described, the machinery is capable of turning and finishing various sizes of spokes, etc.

)V hat we claim as our invention and desire to secure by Letters Patent isl. The within described Inode of operating the cutter frame (J) with its cutters (K) and also the emery wheel (72,) and its frame (L) so as to throw them all clear of the spoke (8) after the operation of turning and smoothing, that is to say we claim the employment of the two arms (R R) upon the shaft operated by means of a hand lever (Rm) in the manner and for the purposes set forth.

2. "We claim the adjustable spring rests (N N) when arranged and operating in the manner and for the purposes set forth.

3. We claim the spring arm Spring catch (m) pitman (n) and bent lever (WW) in combination with the lever (K) clutch (I) and rod (Z) all arranged and operating so as to throw the pulley wheel (H) in and out of gear with the shaft (G) substantially in the manner and for the purposes herein set forth.

In testimony of which invention we have hereunto set our hands.
